HEATER AND ILLUIVIINATOR.

SPECIFICATION forming part of Letters Patent No. 576,434, dated February 2, 1897.

Application filed M rch 17, 1896.

T0 aZZ whom it may concern:

Be it known that I, EDWARD DUMMER, a citizen of the United States, residing at Auburndale, in the city of Newton, county of Middlesex, and State of Massachusetts, have invented a new and useful Heater and Illuminator, of which the following is a specification, reference being had to the accompanying drawings.

The object of my invention is to so combine a burner for gas or oil with a heat-radiator or a deflector for the heated air and reflectors for the light that the heat willv be cliffused and the light be directed as desired, or, more partic ularly, that the heat will be thrown out at a low level, as near the floor of a room, while the light will be reflected at a higher level, so as to be properly directed in the room or part thereof to illuminate, as required.

In the drawingstwo sheets-Figure 1 is an elevation, and Fig. 2 a vertical section, of a device embodying a gas-burner; and Fig. 3 is an elevation, and Fig. 4 a vertical section, of a device embodying an oil-burner, the several figures illustrating my invention. Fig. 5 shows a modification.

Referring to Figs. 1 and 2, a suitable pedestal A supports a gas-burner B. The gas is conveyed to the burner by means of a pipe C, which may serve also as a support for other parts of the device. By means of a flexible tube a the pipe 0 may be connected with another gas-pipe, as is customary with a droplight. The burner B may thus be located very near the floor of a room. So situated as to be below and at the sides of the flame is a reflector D (preferably a parabolic reflector) to reflect the rays of light upward. I have shown a tube or chimney b as forming one piece with the reflector D.

At a suitable distance above the burner is a deflector E for the heated air, and which is also a heat-radiator. This deflector is supported and made adjustable by means of an arm 0, which engages with a support on the pipe 0 and is secured to the same by means of a screw d. A part of the deflector E is transparent or translucent, so that the rays of light will passthrough the same.

The form of the deflector and radiator may be varied to suit special requirement, always, however, operating to direct the heated air Serial No. 588,626. (No model.)

and dilfuse the heat through a space low down and to allowthe light to pass through the same or part thereof. Ordinarily I prefer to have the deflector and radiator circular and to have the central part thereof transparent or translucent, consisting simply of a plane glass disk 6, (though it may be a lens, as shown at e in Fig. 5,) which may be readily removed to clean the same.

Located above the deflector or radiator is a reflector F, which is also adjustable by means of an arm f, which engages with a support or the pipe 0 and a screw 9. This reflector may be of the required form to direct the light to any desired point, always, however, receiving the rays of light which pass through the heat deflector or radiator, and reflecting them at a location higher than that which receives the heat directly. Ordinarily the reflector F will be circular, as shown, and of a form to direct the light onto a book or work in the hands of a person sitting near the device.

Referring to Figs. 3 and a, a burner B", a reflector D, preferably parabolic, below and at the sides of the flame, a heat deflector or radiator E, having a transparent or translucent disk e, and a reflector F above the deflector or radiator, are located with reference to each other substantially as in Figs. 1 and 2. The pedestal A is constructed, however, to support a lamp G, and standards 7t are provided as supports. I have shown in connection with the lamp an ordinary glass chimney i, and also the disk 6 at a considerable higher level than the remainder of the deflector or radiator. There is also shown a table H at the ordinary level and supported by the standards h, the diskc being surrounded by the same and at about the same level therewith. It may sometimes be desirable to inclose the beam of light as much as possible between the deflectors. The tube b (in Figs. 1 and 2) b (in Figs. 3 and 4) will serve this purpose below the deflector or radiator, and a tube I,

Figs. 3 and 4:, above the deflector and table.

That part of the device which comprises the burner, tube about the same, and the heat deflector or radiator may be regarded simply as a stove wherein, by means of the flame, heat and light are produced. Therefore an oil or gas stove provided with an upper part which is transparent or translucent and with suitable reflectors to direct the light through said transparent or translucent part and from a higher location would involve my invention.

It is important that the source of heat and the lateral movement of the heated air be as low down in the room as possible, while for useful effect the light should be thrown from a much higher level. By means of my invention these results can be attained with one flame, which does both the heating and lightin g. In the drawings the course of the heated air is indicated by the broken arrows and that of the light by the other arrows. A person seated near the device will receive heat directly from a source most effectively located and receive light so directed as to be most available, while the device is in other respects useful and may be ornamental.

I claim as my invention- 1. The combination of a burner, a transparent or translucent heat deflector or radiator situated above the burner, and a reflector situated below the burner and adapted to reflect the light toward the deflector or radiator, whereby the light from the flame at the burner will be reflected upward through the heat deflector or radiator, and the heated air will be deflected and the heat radiated at a lower level, substantially as specified.

2. The combination of a burner, a transparent or translucent heat deflector or radiator, and two reflectors, said burner, deflector or radiator and reflectors being so situated with reference to each other that the light from a flame at the burner will be reflected by one reflector upward through the deflector or radiator and onto the other reflector, and the heated air will be deflected and the heat radiated at a lower level, substantially as specified.

3. The combination of a burner, an adjustable heat deflector or radiator which is transparent or translucent, and two adjustable reflectors one above and the other below the burner and the deflector or radiator, so that the light from the flame at the burner will be reflected by one reflector upward through the deflector or radiator onto the other reflector, and the heat and air heated by the flame will be thrown out at a lower level, substantially as specified.

l. The combination of a burner, a chimney for the current of air heated by a flame at the burner, a transparent or translucent deflector above the chimney and burner to throw out laterally the heated air, a reflector to reflect the light upward through the deflector, and another reflector above the deflector to receive and reflect said light, substantially as specified.

5. The combination of a burner, a heat deflector or radiator above the burner to throw out laterally the air heated by the flame at the burner, and provided with a removable transparent or translucent part, and a parabolic light-reflector at the burner to reflect the light from said flame upward through said transparent or translucent part of the heat deflector or radiator, substantially as specified.

6. The combination of a table having an opening, a burner below the opening, a heat deflector or radiator situated below the table and above the burner, apart of the deflector or radiator coinciding with said opening and being transparent or translucent and alightreflector at the burner to reflect the light upward through said opening and through the deflector or radiator, substantially as specified.

7. The combination of a table having an opening, a burner below the opening, a heat deflector or radiator situated below the table and above the burner, a part of the deflector or radiator coinciding with said opening and being transparent or translucent, a light-reflector at the burner to reflect the light upward through said opening and through the deflector or radiator, and a lightreflector above said table in position to receive and reflect the said light, substantially as specified.

EDWARD DUMMER.
